i met a problem with iphone simulator application directory, when i run the application everytime, the name of application directory was changed each of time,can anyone tell me
If you simply relaunch the app from within the simulator springboard it will keep using the same directory. If you rebuild the app in Xcode it will move, and there is no way to prevent that. Xcode should migrate any data you have from the old directory to the new directory when it installs the new build.
